Abstract

The invention relates to a closing device (71), wherein the closing cylinder (70) comprises a free bushing (20) and a core (10) that is provided with followers (15). The free bushing (20) is rotationally mounted in a housing (30). Normally, said bushing is rotationally fixed by a spring-loaded locking and controlling member (61') pertaining to an overload interlock (60). The closing functions are carried out by means of a working member (50) that co-operates with a rotationally fixed displaceable slider (40) that is arranged in the working member (50). In order to create a space-saving device (71) that has a low axial construction height, the locking and control member (61') is placed in a radially free position and loading is carried out directly by means of a blade-shaped spring (37). This enables the locking and controlling member (61') to be displaced independently from the slider (40) in a section of the cylinder where the followers (15) are also arranged. An axial connection (80) allows the spring loading to be transmitted from the overload interlock (60) to the slider (40).
